Answer 2

Answer:

$\frac{1}{ \sqrt{7 - \sqrt{5} } }$

$\frac{1}{ \sqrt{7 -} \sqrt{5} } \times \frac{ \sqrt{7} + \sqrt{5} } { \sqrt{7} + \sqrt{5} }$

$\frac{ \sqrt{7} + \sqrt{5} }{ { \sqrt{7} }^{2} - { \sqrt{5} }^{2} }$

$\frac{ \sqrt{7} + \sqrt{5} }{7 - 5}$

$\frac{ \sqrt{7} + \sqrt{5} }{2}$

This is the answer . Hope it will help u .
